How to check parameter error in Web API

Question

Hello Appian People, 
 
 I have a test WEB API(POST) in order to test my integration process. 
 I also created a test datastore. 
 { 
 user: 
 address: 
 } 
 Please see picture

So what i want to happend is that what to add a test process condition: 
 If the Request result normal, and statusCode 200 - body: received value will be "0" 
 Incase parameter error,and statusCode 200 - body: received value will be "1" 
 
 Anyone has any idea to add this test condition in my Test web API?

Hi peanut 
 If there is any parameter error , we cannot give 200 as status code , we can give 400 status code with bad request as response message. 
 Please refer the below sample code: 
 if(
 or(
 a!isNullOrEmpty(local!value.user),
 a!isNullOrEmpty(local!value.address)
 ),
 a!httpResponse(
 statusCode: 400,
 body: "Few parameters are missing-Bad request"
 ),
 a!writeToDataStoreEntity(
 dataStoreEntity: "DATASTORECONST",
 valueToStore: {"VALUES"},
 onSuccess: a!httpResponse(
 statusCode: 200,
 body: "Response for Sucess"
 ),
 onError: a!httpResponse(
 statusCode: 500,
 body: "Internal server Error"
 )
 )
)
